On a new class of Meromorphic multivalent functions defined by fractional differ-integral operator

الملخص EN

In this work, we submite and study a newlclass of meromorphiccmultivalent functions defined by fractional differ-integral operator .

We gain some geometric properties , such as, coefficient inequality, growth and distortion bounds, convolution properties, integral representation, radii of starlikeness and convexity, extreme points, weighted mean and arithmetic mean for functions belonging to the class
